Google Inc. has quietly patched a potentially dangerous security flaw in two of its business-facing services after a private security research outfit warned that malicious hackers could exploit the bug to hijack sensitive user information.

The vulnerability was flaggedâ€”and fixedâ€”in the Google AdWords and Google Services subdomains.

Because both sites use data from the Google Accounts username/password system, security experts said the flaw presented a major identity theft risk.

As if click fraud wasn't a bad enough issue. As they continue to collect and cross reference information they need to be careful with that user privacy issue.
